When no E15 rod may be reciprocated with great rapidity. The striking Solenoid being more powerful will more the Striking element or rod 16 forwardly with considerable force, while the returning solenoid 15, being ot a less power, will move the striking element or rod lo, in a reverse direction, sutiicientljquickly without near as much force, whereby the apparatus is not subjected to undue shocks and jars upon the return movement ot the striking,` eleinent or rod 1G. When the Switch 4l is closed the current is Supplied directly to the solenoids 14 and '15, while the supply ot current to the motor 37 is controlled by the rheostat f-l-, whereby the saine will be made to operate at a desired speed.

lt is to be understood that the form ot' my inwntion he ewitli shown and described is to bc taken as a preferred example ot' the flame, and that certain changes in the shape, and arrangement ot parts may be re- .fioi ted to without departing lroin the spirit ol' the invention or the Scope ot the sul)- joined claim.

Vl' l a vingJ described my invention, I claim in apparatus ot the character described, a tubular casing adapted to be conveniently handled by a Single operator and having;1 a central enlarged.'portion provided with lati erally contracted forward and rear end the lorward laterally contractportion being; adapted to be held in one hand et' the operator, a reriprocaiory tool mounted within the torward laterally contracted portion, a relatively sstrong; :solenoid winding,` disposed within the central enlarged portion ot the tubular cucine', a relatively weak solenoid winding" arranged within the rcarlaterally contracted end portion ol" the tubular casing, a reciprooatory core common, to both solenoid windings to engage the tool, an electric motor mounted upon the rear end portion ol the tubular canine; with its armature shaft extending); longitudinally ot and parallel with the laterally contracted rear end portion, n A,-olcnoid .rindings, circuit opening and closine` dern-.es connected in the circuits and with thel armature Shaft tor rotation thereby, means vl'or connccting,;` said motor `in the circuits, and a. transverse handle connected with the Vree end ot' the rear laterally redicr-il .amd portion ol the tuhular casing.
